Effects of vitamin and multiple micronutrient supplementation for pregnant and/or lactating women on maternal and infant nutritional status in low- and middle-income countries: a systematic review and meta-analysis.

ABSTRACT:

Background

Globally, over half of women of reproductive age are affected by at least one micronutrient deficiency, often exacerbated during pregnancy and lactation, contributing to adverse maternal and child health outcomes. This systematic review and meta-analysis synthesized impact of vitamin supplementation on maternal, infant and lactational nutritional status in low- and middle-income countries.

Methods

MEDLINE, EMBASE, CENTRAL, and WHO library databases were searched. Eligible studies included randomized controlled trials of micronutrient supplementation in healthy pregnant/lactating women, assessing maternal/infant micronutrient status or milk composition. Random-effects meta-analysis was performed for outcomes with ≥2 studies, and evidence quality was evaluated using
